2. Absorption technology recovery of fuels tested in pilot plant AP-2, 
simulating the work of filling PS tanks. It is based on the displacement of diesel 
fuel vapors into the atmosphere out of the «intermediate» tank by petrol vapors or 
absorption of them.
Its composition (Fig. 3): a tank of 25 m

with petrol (1), 
«intermediate» tank with diesel fuel, 25 m

(2), a gas binding (3), backpressure 
valve (4), input unit SAM into «intermediate» tank (5), the receiving of diesel fuel 
(6). When filling the tank (1) SAM from pipeline (3) through a backpressure valve 
(4) enters into the tank (2) with a diesel fuel. Input unit (5) provides contact petrol 
vapors with diesel fuel at the bottom of the GS and the absorbance in the tank (2). 
The excess of diesel fuel vapors is vented into the atmosphere. To reduce

absorption time, the tank 2 was equipped by receiving unit (6), in countercurrent, 
during discharge of fuel. As the concentration of hydrocarbons in the SAM of tank 
with diesel fuel is lower than in the tank with petrol, the adsorption of petrol vapor 
and reducing their emissions into the atmosphere are achieved.
